Letters Patent No. 94,337, dated August 31, 1869.

. BRICILMAQHINE.

'lhe Schedule referred to in lthese Letters Patent and making part of .the same.

To all w'hom it ma'j conce/m Be it known that I, Juntos FREDERICK Moons POLLOCK, of Manchester, `in England, have invented a new and i-mproved Brick-PressingMaehine; and I do hereby declaret-hat the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, refer ence being had to the accompanying drawings, vforming part of this specication, in which- Figure'l, Sheetl, is a vertical section of my ixuproved machine.

Figure 2, Sheet l', is a detail sectional view of'the same, taken through the line. a: a', g. 1.

proved `machine for pressing brick, which shall be simple in construction, eiiective in operation, and convenient in use; and

l It consists in the construction and combination of the various parts of the machine, as hereinafter more fully described.

A represents the frame of the machine. v B is the drtving-shaft, which revolves in bearings in the iianic A, andwhich receives motion'from any unlvenient line of shafting, by means of a band passing around the pulley C, attached to the said shaft To the shaft B is attached a bevel gear-wheel, D, the teeth of which mesh into Vthe teeth of the bevel gear-wheel E, attached to the shaft-"F, which revolves in bearings in supports attached to the frame A, and to the other ond of which is attached a bevel gearwheel, G; v

The teeth 'of the. bevel gear-wheelV G mesh into the teeth ofthe .bevel gear-wheel ll, attachedfto the journal of one 'oi' the rollers l, around which passes the endless apron J, by which the pressed bricks are carried away from thc machine.

Upon the side of the bevel gear-wheel D is formed a cam-groove, d, into which enters the crankepin of the crank K, attached to the end of the shaft L, which works in supports attached to the frame A of the machine, and to which is rigidly attached the lower end of the arm or bar M, the upper end of which is pivotcdtothe follower N ,by means'of which the moulded 4bricks are fed into the press.

O is the die, by which the bricks are pressed into ,he desired form, and which is securely attached to he bar P; te the ends of which are rigidly attached the upper ends ofthe rods or bars Q, which pass down through holes in the bed-plate R, and the lower ends oi' which are rigidly attached to' the cross-head S of the piston-rod 'l of the steam-cylinder U, so that the die may be operated to press the brick by the movementof the piston of said cylinder.

V is the steam-chest, the valve-stem W of which terminates with a cross-head, X, the arms of which are at different elevations, and which extend up between the two cams Y attached to the shaft B, in such positions that they may act upon the cross-head X to open and close the valves iu vsaid steam-chest, at the proper times, to raise and lowerthe die O.

Z -is the lower die, which is placed in a socket in the bed or die-plate R, and rest-s u'pon flanges formed upon the inner sides of said socket, as shown in iig. 2.

l Upon the lower side of the die Z, are formed arms, which extend downward into such a. position that the cross-head S, as it rises, may raise the die Zand the pressed brick, so that the fadvanceioi' the next brick may push the pressed brick upon the `carrier J, by which it is removedfrom the machine. Y

.lf desired, the dies and the die-plate may be covered and protected by a cap or case, as shown at figs. 4 and 5..

In case there is no convenient line of shafting, the shaft Ii may be operated by :if small steam-cylinder, A', the cross-head B o fthe piston-rod C' of which works in guides D, and to it is pivoted the end ofthe pit-man E, the other end of which is pivoted to the crank-pin of the gear-wheol Il, the journals of which workin bearings attached to thc'frame A, and the teeth of which mesh into the teeth of the gear-wheel G', attached to said shaft B, as shown in fig. 5.

Having thus described my invention, I claim as new, and desire to secure by Letters I atent- ,1. The arrangement of the drivin gishaft 13, cams Y, cross-head X, valve-stem W, steam-chest V, steamcylinder U, pistonqed T, cross-head S, rods Q, cross- I head or bar 1, dies O Z, and bed or die-plate R, substantially as herein described, for the purpose specified. 2. The described arrangement, with relation to the cam gear-wheels D, the dies O Z,and` bed-plate R, of the crank' K, pitman M, and feeder N,thc shaft F, gea-rwlieels E G H, and endless carrier J, for the purpose specified.

The above specification of my invention signed by me, this 7 th day of December, 1868. JULIUS FREDERICK MOOREVPOLLOOK. Witnesses:
